I've got a question that's only slightly relevant, but let me ask anyway: say a baby is Baptized and Chrismated in the Orthodox Church, and later in life decides to become Catholic. I understand that Protestants are usually received by Confirmation, but the Orthodox person has already been validly Baptized and Chrismated (that counts as Confirmation, right?)

So, is there a special rite or ceremony by which an Orthodox person is received?

Since all of the Orthodox Sacraments are valid, and Chrismation does equate to Confirmation (and cannot be repeated), there is really nothing to be done sacramentally for the person you describe in your example. An Orthodox convert to Catholicism is received simply with a formal profession of faith. A documentation of the Sacraments received prior to conversion would almost certainly be requested, and this would be handled simply with a certificate or copy of an official ledger from the Orthodox parish(es) involved.

So, is there a special rite or ceremony by which an Orthodox person is received?

They just make a profession of faith.

Someone who is received from Eastern Orthodoxy automagically becomes a Byzantine Rite Catholic, not a Latin Rite Catholic. If they really want to become a Latin Rite Catholic (e.g., because they want to eventually seek ordination as a Latin Rite cleric), they would have to petition the Holy See for a formal change of rite.
